Threaded Mounting
Note: When mounting the flow element, use a lubricant or sealant applied to the male threads of all NPT
connections. The lubricant or sealant and process environment should be compatible. Make sure all
the process connections are tight. To avoid leaks do not over tighten or cross-thread the connections.
1. Verify end hardware is loose if present. Carefully insert the flow element into the process mount. Align the
flow element with the end support if present.
2. Verify that the process media is in the same direction as the FLOW ARROW on the FLAT that is near the local
enclosure.
3. The threads are right-handed. Place pipe wrench on un-threaded portion of metal shaft. Rotate until snug and
continue to turn until the FLAT is parallel to the process flow. Apply even pressure so as not to disfigure the
nipple.
Caution: Do not apply any leverage to the local enclosure itself.
4. Tighten all connections. Tighten all end hardware if present.
Flanged Mounting
1. Verify end hardware is loose if present. Carefully insert the flow element into the process mount. Align the
flow element with the end support if present.
2. Attach the process mating flange with care. Maintain the correct orientation of the flow element to ensure
flowmeter accuracy.
3. Verify that the FLOW ARROW points in the same direction as the process media flow, and the FLAT is parallel
to flow.
4. Apply the appropriate gasket and/or sealant to the flange mount faces as required.
5. Attach with a bolt, two flat washers, lock washer and nut for each bolt hole; apply lubricant/sealant to male
threads and torque. For correct hardware and torque, refer to ANSI B16.5 specifications.
6. Tighten all of the connections.
Install Flow Transmitter
Caution: For flow elements in explosive environments, isolate the conduit before it leaves the environment.
Use a potting "Y" to provide the isolation.
Mounting the Remote Enclosure
Figure A-1 shows the flowmeter enclosure with the physical dimensions for mounting of the flow transmitter
enclosure.
Note: The factory recommends removal of the flow transmitter control circuitry while pulling the necessary
cables; this will prevent damaging electronic components. To remove the circuit boards unbolt the four
outermost screws on the mounting plate.
